A Group Effort that Grew

Group effort from poliovirus

Group effort from poliovirus he pathogenesis of poliovirus relies on virus diversity per se, not the selection of any particular adaptive mutation, say Marco Vignuzzi, Raul Andino (UCSF, San Francisco, CA), and colleagues. Different variants may achieve different tasks in a group effort to navigate the host environment. This is how a quasispecies, or group of variants, is meant to behave, based...

The Child Who Never Grew

Grew : un outil de réécriture de graphes pour le TAL (Grew: a Graph Rewriting Tool for NLP) [in French]

Grew: a Graph Rewriting Tool for NLP We present a Graph Rewriting Tool dedicated to NLP applications. Graph nodes contain feature structures and edges describe relations between nodes. We explain the Graph Rewriting framework we use, the implemented system and some experiments. MOTS-CLÉS : réécriture de graphes, interface syntaxe-sémantique.

Effort in the face of difference: Feeling like a non-prototypical group member motivates effort

Three studies examined the relationship between individuals’ perceived “prototypicality” in a group, their subsequent self-presentation goals, and individual effort in that group. Consistent with the finding that feelings of marginal ingroup membership status elicit a desire to seek stronger social connections within ingroups, we predicted that non-prototypical group members will have more sali...

A generalization of the probability that the commutator of two group elements is equal to a given element

The probability that the commutator of two group elements is equal to a given element has been introduced in literature few years ago. Several authors have investigated this notion with methods of the representation theory and with combinatorial techniques. Here we illustrate that a wider context may be considered and show some structural restrictions on the group.
